Vibration and noise reducing field.
Background technology
At present, there have been highly developed vibroshock, vibration isolator, but applied these vibroshocks and vibration isolation under water
During device, vibration damping and the limited capacity of vibration isolation, this is to be caused by the reason of the following aspects: one, air quality and damping system
Number is the least, and vibroshock and vibration isolator are the most hardly with considering, and the quality of water is compared with damped coefficient and wanted for air
Much bigger;Two, the rubber shock absorber in air and vibration isolator are when being applied under water, it is easy to by water corrosion, particularly
Rubber needs special gluing to connect on a metal plate, and these glue, through long period of soaking, easily cause rubber and come off, be substantially reduced vibration damping
Performance with vibration isolation;Three, the rubber shock absorber in air and vibration isolator can be by buoyancys in water, corresponding mass effect
Weaker, the decline of its vibration damping and anti-vibration performance is affirmative;Four, the vibroshock in air, non-especially with rubber etc.
During uniform dielectric, owing to the parameters such as its density, speed and damping are not constants, it is difficult to use computed in software vibration damping and the property of vibration isolation
Can, and can only be by way of experimental test, the development process of vibroshock and vibration isolator that this is the most sluggish.Owing to sound insulation under water hinders
The isolation frequency that plate needs is 4kHz-8kHz, and therefore, vibroshock and vibration isolator in these air are not suitable for supporting under water
Sound insulation baffle.
Chinese patent " a kind of stacked metal isolator " (patent No. 201210317448), utilize metal-rubber as elastomer,
But this stacked metal isolator needs the driving frequency according to power-equipment and quality etc., determines the number of vibration isolator elastomer
Amount and vibration isolator quantity, be not an easy vibration isolator.
Chinese patent rigid metal vibration isolators such as " a kind of " three-dimensionals (patent No. 201210449640), has in X, Y, Z-direction
Identical rigidity, is suitable for protecting the rigidity vibration isolation such as electronic equipment is carried out, is not appropriate for the sound insulation baffle supported under water.
